SBT, SBT-F

  • Designed to work even without lubrication.
  • Wide range of temperature .
  • High level thermal conductivity.

The SBT-bearings are mainly intended for oscillating movements, bearing places with often occurring starts and stops.

SBT-bearing is a 3-layer bearing, wrapped of copper plated steel-sheets with a layer of PTFE. The SBT-bearings are mainly intended for oscillating move-ments, bearing places with often occurring starts and stops, or when minimal dryfriction is tried to be obtained and when greasing is out of the question.

Owing to the fact that the friction is very low, SBT-bearings can be used without additional lubrication. SBT-bearing is resistant to most common mediums. The thin layer, which makes up the running surface, should be well protected to avoid mountingdamages and also protected from heat e.g. welding.
